Functional MRI of stimulus interference on auditory processing in normal listeners and tinnitus patients

We are constantly immersed in stimuli. Upon reaching our senses, stimuli are processed within various brain systems along various pathways into the brain, and eventually turned into a percept. However, there are percepts that do not result from responses to external source stimuli. A particular case of this situation is the auditory percept known as tinnitus. Tinnitus can be seen as a task-irrelevant auditory percept, commonly reported to interfere with normal daily tasks. This is known from reports made by tinnitus sufferers that refer to their phantom percept as distracting, and that it diverts their focus from the task-relevant stimuli.(...)

The late adopter scale: A measure of late adopters of technological innovations

Diffusion of Innovation is a topic of interest for researchers and practitioners. Although substantial research is conducted on user categories, researchers often focus on the first half of the curve, ignoring the late adopters. We conduct two studies to measure the attributes of late adopters. In our first study of mobile phone users, we develop the Late-Adopter Scale. We then test it on a sample of laptop users. This scale is multi-dimensional, presents nomological and discriminant validity and has three dimensions: 1) rate of adoption, 2) resistance to innovation, and 3) skepticism. Findings reveal that all three Late Adopter Scale dimensions are significantly associated with low price preference. Moreover, in both samples skepticism is associated with high preference for simple products, lower leading edge status, and lower product involvement. Discussion focuses on implications of this new scale to theory and practice of new product development and diffusion of innovation.

Weimar and the crisis of political legitimacy in Late Modernity : Max Weber, Hans Kelsen and Carl Schmitt

Através da comparação das ideias de três grandes teóricos da política no conturbado contexto da República de Weimar, esta dissertação pretende reconsiderar a crise da legitimidade política na modernidade tardia. Tal crise é concebida tanto em sentido estrito, enquanto crise das democracias liberais perante os efeitos de rápidas mudanças sociais e a emergência da política de massas, como em sentido lato, ou seja, enquanto crise dos alicerces político-intelectuais da era moderna. Nessa medida, veremos como os juízos de Weber, Kelsen e Schmitt não se limitam a veicular veredictos contrastantes sobre a democracia de massas, o parlamentarismo e os partidos políticos, remetendo também para narrativas distintas sobre o destino do homem moderno – narrativas que oscilam entre o optimismo moderado, a ambivalência e a reacção hostil.
